As Greg Skinner mentioned, FTP also is in curl.
telnet is also in curl, but if that is not enough, try screen (*):
$ screen telnet ietf.org 80
Add
zombie ^\^]
to your ~/.screenrc to retain the screen window after the connection is closed; Ctl-\ then destroys (closes) the screen window, Ctl-] resurrects it (reopens the connection in the window).
Use
$ info screen
to learn more about screen and find the command line options and commands you may want to use.

(*) We had handed over screen to a different maintenance team before this was added to screen, so I’m just reporting this.
screen (/usr/bin/screen) is in macOS:
$ screen -v
Screen version 4.00.03 (FAU) 23-Oct-06
$ sw_vers
ProductName: macOS
ProductVersion: 14.6
BuildVersion: 23G80
Apart from introducing right in the 1980s a way to keep a connection open during absence, screen is also alive and well as the no-software-installed way to talk from a Mac to IoT devices via serial over USB:
$ screen /dev/cu.usbserial-142210 115200
